Guilty Pleasures — Donna Hill

Jake and Eva Kelly are masters at what they do. From the sex games they play with each other to the cons they pull on their unsuspecting marks, they are unstoppable. To the outside world, Jake and Eva are just another young buppie couple living their dream under the bright lights of New York City. Life is good, money is flowing, and living is large. They couldn't ask for more---until Jake gets greedy. Only this time they pick the wrong mark. The tables have turned and their addiction to the game could cost them everything---even their lives.
Now Jake and Eva are forced to pull off the sting of their careers. With the help of Jake's brother Jinx and Eva's look-alike cousin Rita they board a cruise ship from Brazil to take down Xavier Suarez, one of the most notorious figures in the underworld. From the streets of New York City to the steamy tropics of Brazil, from the coast of Miami to the paradise of Hawaii, they hatch a plan with no room for errors.
With the FBI hot on their trail and under the threat of Suarez's unspeakable wrath, every trick they've ever learned comes into play. But it is their own dark past that threatens their future, and the secret that Eva harbors that could ruin everything.
